Most designers believe that they are designing with performance as a primary concern. Why then, are systems deplozed that are significantly slower thet anticipated, sometimes resulting in a complete design ocerhaul to meet performance needs? Experience suggest thet the reasons are two-fold: (1) A failure to focus at an architectural level when designing for performance, (II) An inability to gather requisite performance metrics early enough in the design cycle to affect the development outcome. Yhe paper recommends two approaches that adress these failings: 1) How to focus on total szstem throughput based on Use Case scenarious when designing for performance, and 2) How to create an architectural prototype that is used to gather performance metrics prior to making firm design decisions"},{"@xml:lang":"sl","#text":"Le redki vidiki razvoja sistemov povzročajo toloko skrbi razvijalcem in tolikoslabe volje uporabnikom kot zmogljivost. Razvijalci zvečine mislijo, da pri razvoju poskrbijo za največjo možno zmogljivost. Zakaj se torej uporabljajo sistemi, ki so znatno počasnejši kot je bilo pričakovano, tako je včasih potrebno zasnovo popolnoma prenoviti, da bi dosegli ustrezno zmogljivost? Izkušnje kažejo, da sta za to dva razloga: 1) V želji, da bi imelsistem kar največjo zmogljivost, se razvijalci ne usmerjajo na določeno raven arhitekture, 2) Razvijalci nimajo možnosti, da bi že med razvojem sistema pravočasno preverili njegovo zmogljivost in tako prilagodili rezultat razvoja. Članek priporoča dva načina reševanja teh slabosti: 1) Upoštevali naj bi delovanje celotnega sistema na temelju scenarijev možne uporabe in 2) Še pred dokončno odločitvijo o njegovi zasnovi naj bi zmogljivost sistema preverjali na prototipih"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-RCDKXNAX","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-RCDKXNAX"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-RCDKXNAX/e8e0c822-4c50-4136-a621-10ac98bbbde5/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Slovensko društvo Informatika"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-RCDKXNAX/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-RCDKXNAX"}}}}
